Description

Technical Field

[0001] This invention belongs to the field of cutting device technology, and particularly relates to an alloy saw blade for cutting logs and its cutting device. Background Technology

[0002] The core application of alloy saw blades and their cutting devices for log cutting is in the squaring, cutting, and precision cutting processes of logs in wood processing plants. This directly affects the dimensional accuracy, surface quality, production efficiency, and raw material utilization rate of wood processing. As the core cutting component of log cutting devices, alloy saw blades undertake the key task of cutting logs into square timber, boards, or fixed-length materials according to specifications. Their structural design, material properties, and the precision of their matching with the cutting device directly determine the flatness, smoothness, and stability of the cutting surface.

[0003] Currently, most log squares on the market are processed using large band saws. The working principle is as follows: the drive device drives the ring saw blade to rotate at high speed, and the saw teeth on the saw blade are used to continuously saw the logs. The feeding mechanism is used to feed the logs and cut them into shape.

[0004] Currently, most logs on the market are squared using large band saws, which generally have low processing precision. After sawing, the wood surface may have ripples, requiring subsequent sanding and other fine finishing. Furthermore, this method requires high operational skills, as operators need to be proficient in adjusting the saw blade tension and feed speed; otherwise, deviation and chipping are likely to occur. At the same time, the equipment investment cost is high, with large band saws being expensive, and the subsequent costs of saw blade maintenance and replacement are also not low. In view of this, we propose an alloy saw blade for log cutting and its cutting device. Summary of the Invention

[0005] The purpose of this invention is to provide an alloy saw blade for log cutting and a cutting device thereof, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides an alloy saw blade for cutting logs, comprising: The device comprises two main blade bodies, each with several mounting slots. Each mounting slot contains a blade holder base, which is fixed to the mounting slot by several blade holder base fixing screws. Each blade holder base has a blade cover, and a double-sided crushing blade is positioned between the blade holder base and the blade cover. Each blade cover has two positioning screws, one end of which passes through the blade cover and the blade holder base and extends to the inner wall of the mounting slot, where it is threadedly connected. Each blade cover also has two blade fixing screws, one end of which passes through the blade cover, the double-sided crushing blade, and the blade holder base and extends to the inner wall of the mounting slot, where it is threadedly connected. Two cutting saw blades are respectively disposed on one side of two main blade bodies. Each cutting saw blade is provided with a plurality of cutting saw blade fixing screws, and one end of each cutting saw blade fixing screw passes through the main blade body and extends into the main blade body to be threadedly connected to the main blade body.

[0007] This technical solution completes the entire process of high-precision square cutting of logs, immediate crushing of cutting residue, and automatic chip removal in one go, fundamentally solving the technical pain points of low processing precision, easy deviation, and cumbersome residue handling of traditional band saws.

[0008] In the above technical solution, the main blade body is made of 7075 aluminum, and the two positioning plug screws and the two blade fixing screws are connected to the blade seat base, the double-sided crushing blade and the blade cover.

[0009] In this technical solution, the main blade body is made of 7075 aluminum, which significantly reduces the overall weight while meeting the requirements of high strength and high impact resistance, lowers the spindle rotational inertia, improves the equipment's response speed and operational stability, and reduces motor energy consumption and bearing wear. Two positioning plug screws and two blade fixing screws are inserted and fitted with the blade holder base, double-sided crushing blades, and blade cap to form a precise and reliable integrated positioning and fastening structure. The positioning plug screws provide precise circumferential and radial positioning, ensuring accurate installation of the double-sided crushing blades and uniform blade clearance, effectively avoiding uneven crushing and cavity scraping. The blade fixing screws provide a stable axial fastening force, preventing the blades from loosening, deflecting, or even falling off under high-speed rotation and material impact, ensuring safe equipment operation.

[0010] In view of this, the present invention provides a cutting device for log cutting, comprising a cutting device and two output shafts, characterized in that it further comprises: Two main blades are respectively located on the side of the two output shafts that are close to each other. Each of the two main blades has a slot that communicates with the outside world. Each of the two slots has a plug that is fixedly connected to the output shaft. A plurality of positioning slots are formed on the inner wall of the slot, and a positioning block is inserted into each of the plurality of positioning slots, and the plurality of positioning blocks are fixedly connected to the periphery of the insertion block.

[0011] In this technical solution, several positioning slots are formed on the inner wall of the slot, and positioning blocks are inserted into each of the positioning slots. The positioning blocks are fixedly connected to the periphery of the insertion blocks, which can realize precise circumferential positioning between the insertion blocks and the main blade body. This effectively prevents the main blade body from rotating relative to the main blade body during high-speed rotation, greatly improves the stability and coaxiality accuracy of the transmission connection, and ensures the smoothness of the cutting operation. The main blade body is made of 7075 aluminum, which significantly reduces the rotational load of the output shaft, reduces vibration and inertial impact during high-speed operation, greatly improves the stability of the cutting process, and ensures the flatness and smoothness of the cut surface.

[0012] Furthermore, the above technical solution also includes: Several limiting grooves are respectively formed on the periphery of the two insert blocks; A plurality of sliding grooves are formed on the periphery of the slot, and a rod is slidably connected in each of the plurality of sliding grooves. One end of each rod extends into a plurality of limiting grooves and is inserted into each of the limiting grooves. A screw is threaded into each of the plurality of rods. Two drive components are located in two main blade bodies and are used to drive a number of corresponding screws to rotate.

[0013] This technical solution ensures that users can quickly fix the main blade onto the insert block, or quickly release the main blade from the block, allowing users to replace the main blade.

[0014] In the above technical solution, the driving component further includes: Several first gear slots are formed in the main cutter body and are respectively connected to several sliding grooves. A first bevel gear and a second bevel gear are rotatably connected in each of the several first gear slots, and the first bevel gear and the second bevel gear mesh with each other. One end of each of the several first bevel gears extends into the several sliding grooves and is respectively fixedly connected to several screws. A plurality of rotating slots are formed in the main blade body and are respectively connected to a plurality of first gear slots. Gears are rotatably connected in each of the plurality of rotating slots, and one end of each of the plurality of gears extends into the plurality of first gear slots and is respectively fixedly connected to a plurality of second bevel gears. An annular groove is formed in the main blade body and is connected to several rotating grooves. A toothed ring is rotatably connected in the annular groove, and the toothed ring meshes with several gears. A rotating rod is fixedly connected to one of the gears, and one end of the rotating rod passes through the inner wall of one of the rotating slots and extends to the outside.

[0015] In this technical solution, it is ensured that the user can drive several screws to rotate simultaneously.

[0016] Furthermore, the above technical solution also includes: A fixed sleeve is fixedly connected to one side of the main blade body and sleeved around the circumference of the rotating rod. A threaded groove is provided on the circumference of the fixed sleeve, and a protective groove is threaded onto the threaded groove. A cavity communicating with the outside is provided in the protective groove, and one end of the rotating rod is located in the cavity.

[0017] In this technical solution, the rotating rod is protected from the impact of wood chips.

[0018] In the above technical solution, the rotating rod is rotatably connected to the main blade body, and one end of the rotating rod has a hexagonal structure.

[0019] In this technical solution, the rotating rod is rotatably connected to the main blade body. One end of the rotating rod has a hexagonal structure, which not only ensures the smoothness of the rotating rod adjustment process, but also allows for operation with a standard Allen wrench. The locking and unlocking of the main blade body can be completed without special tools, significantly improving the convenience of equipment maintenance.

[0020] In the above technical solution, one end of the first bevel gear is rotatably connected to the slide groove, and one end of the gear is rotatably connected to the first gear groove.

[0021] In this technical solution, one end of the first bevel gear is rotatably connected to the slide groove, and one end of the gear is rotatably connected to the first gear groove. This ensures that there is no jamming during the operation of each transmission component, and that the power transmission is smooth and reliable. At the same time, it reduces wear between transmission components and effectively extends the service life of the drive assembly.

[0022] In the above technical solution, the screw is located in the slide groove and is rotatably connected to the slide groove, and the threads on the plurality of screws have the same direction of rotation and the same thread pitch.

[0023] In this technical solution, the screw is located in the slide groove and is rotatably connected to the slide groove. The threads on several screws have the same direction of rotation and the same thread pitch, which can ensure that several insert rods move synchronously and at a uniform speed during the adjustment process, so that the locking force of each insert rod on the insert block is uniform and consistent, avoiding the tilting or loosening of the main blade body due to uneven force, and further improving the reliability of the locking structure.

[0024] The beneficial effects of this invention are: 1.

The above-mentioned structural design integrates cutting and crushing functions into the same device, eliminating the need for additional crushing equipment, simplifying the production process and reducing the equipment footprint and overall investment cost.

[0025] 2. This alloy saw blade for log cutting and its cutting device, through the setting of cutting saw blade fixing screws, cutting saw blade and positioning plug screws, blade fixing screws, blade seat base, blade pressure cover, and double-sided crushing blade, realizes the quick disassembly and installation of two core vulnerable parts: the cutting saw blade and the double-sided crushing blade. The replacement operation is simple and convenient, and production can be resumed without complicated debugging. The above structure design greatly reduces the maintenance difficulty and downtime of the equipment, while ensuring the installation accuracy after the replacement of vulnerable parts, and ensuring the long-term stability of cutting and crushing operations.

[0034] Please see Figure 4 As shown, this embodiment provides an alloy saw blade for log cutting, comprising: Two main blade bodies 3 are provided, each with several mounting slots 6. Each mounting slot 6 contains a blade holder base 7. Each blade holder base 7 is fixed to the mounting slot 6 by several blade holder base fixing screws 8. Each blade holder base 7 has a blade cover 10. A double-sided crushing blade 9 is provided between the blade holder base 7 and the blade cover 10. Each blade cover 10 has two positioning plug screws 11, one end of which passes through the blade cover 10 and the blade holder base 7 and extends to the inner wall of the mounting slot 6, where it is threadedly connected. Each blade cover 10 has two blade fixing screws 12, one end of which passes through the blade cover 10, the double-sided crushing blade 9, and the blade holder base 7 and extends to the inner wall of the mounting slot 6, where it is threadedly connected.

[0035] In operation, when the user starts the cutting device 1, the cutting device 1 will drive the two output shafts 2 to rotate, and the two output shafts 2 will drive the two main blades 3 to rotate through the two inserts 5 respectively. When the two main blades 3 rotate, they will drive the two cutting saw blades 13 to cut the log. At the same time, the two main blades 3 will drive several double-sided crushing blades 9 to rotate synchronously at high speed, instantly crushing the edge scraps and large sawdust generated during the cutting process into fine particles. The entire process of high-precision square cutting of logs, instant crushing of cutting residues and automatic chip removal is completed in one go, fundamentally solving the technical pain points of low processing accuracy, easy deviation and cumbersome residue handling of traditional band saws. Example 2:

[0036] This embodiment provides an alloy saw blade for log cutting. In addition to the technical solutions of the above embodiments, it also has the following technical features: the main blade body 3 is made of 7075 aluminum, and two positioning plug screws 11 and two blade fixing screws 12 are inserted and matched with the blade seat base 7, the double-sided crushing blade 9 and the blade pressure cover 10.

[0037] The main blade body 3 is made of 7075 aluminum, which significantly reduces the overall weight while meeting the requirements of high strength and high impact resistance, lowers the spindle rotational inertia, improves the equipment's response speed and operational stability, and reduces motor energy consumption and bearing wear. Two positioning plug screws 11 and two blade fixing screws 12 are inserted into the blade holder base 7, the double-sided crushing blade 9, and the blade cap 10, forming a precise and reliable integrated positioning and fastening structure. The positioning plug screws 11 provide precise circumferential and radial positioning, ensuring accurate installation of the double-sided crushing blade 9 and uniform blade clearance, effectively avoiding uneven crushing and cavity scraping. The blade fixing screws 12 provide a stable axial fastening force, preventing the blade from loosening, deflecting, or even falling off under high-speed rotation and material impact, ensuring safe equipment operation. Example 3:

[0038] Please see Figures 1-8 As shown, this embodiment provides a log cutting device, including a cutting device 1 and two output shafts 2, and further comprising: Two main blade bodies 3 are respectively located on the side of the two output shafts 2 that are close to each other. Each of the two main blade bodies 3 has a slot 4 that communicates with the outside world. Each of the two slots 4 has a plug 5 that is fixedly connected to the output shaft 2. Several positioning slots 15 are formed on the inner wall of the slot 4. Positioning blocks 16 are inserted into each of the positioning slots 15, and the positioning blocks 16 are fixedly connected to the periphery of the insert block 5.

[0039] Several positioning grooves 15 are formed on the inner wall of the slot 4, and positioning blocks 16 are inserted into each of the positioning grooves 15. The positioning blocks 16 are fixedly connected to the periphery of the insertion block 5, which can realize precise circumferential positioning between the insertion block 5 and the main blade body 3, effectively preventing relative rotational offset of the main blade body 3 during high-speed rotation, greatly improving the stability and coaxiality accuracy of the transmission connection, ensuring the smoothness of the cutting operation. The main blade body 3 is made of 7075 aluminum, which significantly reduces the rotational load of the output shaft 2, reduces vibration and inertial impact during high-speed operation, greatly improves the stability of the cutting process, and ensures the flatness and smoothness of the cutting surface. Example 4:

[0040] This embodiment provides a cutting device for log cutting, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes: Several limiting slots 17 are respectively opened on the periphery of the two insert blocks 5; A number of sliding grooves 18 are formed on the periphery of the slot 4. Each of the sliding grooves 18 is slidably connected with a rod 19, and one end of each rod 19 extends into a number of limiting grooves 17 and is inserted into each limiting groove 17. Each rod 19 is threadedly connected with a screw 20. Two drive components are located inside the two main cutter bodies 3, and are used to drive the corresponding screws 20 to rotate.

[0041] When the user needs to replace the main blade body 3, the user drives several screws 20 to rotate within several sliding grooves 18 via the drive component. This causes several insertion rods 19 to move along the sliding grooves 18 under the action of the threads of the screws 20. One end of each insertion rod 19 can be inserted into a number of limiting grooves 17, or from the limiting grooves 17 into the sliding grooves 18. This ensures that the user can quickly fix the main blade body 3 onto the insertion block 5, or quickly release the fixation of the main blade body 3, allowing the user to replace the main blade body 3. Example 5:

[0042] This embodiment provides a cutting device for log cutting, which, in addition to the technical solutions of the above embodiments, also has the following technical features, including a driving component: A plurality of first gear slots 21 are formed in the main cutter body 3 and are respectively connected to a plurality of sliding grooves 18. A first bevel gear 22 and a second bevel gear 23 are rotatably connected in each of the plurality of first gear slots 21, and the first bevel gear 22 and the second bevel gear 23 mesh with each other. One end of each of the plurality of first bevel gears 22 extends into the plurality of sliding grooves 18 and is respectively fixedly connected to a plurality of screws 20. A number of rotating grooves 24 are formed in the main cutter body 3 and are respectively connected to a number of first gear grooves 21. Gears 25 are rotatably connected in each of the rotating grooves 24, and one end of each gear 25 extends into the first gear grooves 21 and is fixedly connected to a number of second bevel gears 23. An annular groove 26 is formed inside the main cutter body 3 and is connected to several rotating grooves 24. A toothed ring 27 is rotatably connected inside the annular groove 26, and the toothed ring 27 meshes with several gears 25. Rotating rod 28 is fixedly connected to one of the gears 25, and one end of rotating rod 28 passes through the inner wall of one of the rotating slots 24 and extends to the outside.

[0043] When the user needs to replace the main blade body 3, the user manually rotates the rotating rod 28, causing the rotating rod 28 to drive one of the gears 25 to rotate in one of the rotating grooves 24. This causes one of the gears 25 to drive several other gears 25 to rotate through the gear ring 27. When the gears 25 rotate, one end of each gear 25 will drive several second bevel gears 23 to rotate in several first gear grooves 21. This causes several second bevel gears 23 to drive several first bevel gears 22 to rotate in several first gear grooves 21. This causes several first bevel gears 22 to drive several screws 20 to rotate in several sliding grooves 18, ensuring that the user can drive several screws 20 to rotate simultaneously. Example 6:

[0044] This embodiment provides a cutting device for log cutting, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and further includes: The fixed sleeve 29 is fixedly connected to one side of the main blade body 3 and sleeved around the circumference of the rotating rod 28.

A cavity 32 communicating with the outside is opened in the protective groove 31, and one end of the rotating rod 28 is located in the cavity 32.

[0045] In use, the user can rotate the protective groove 31 by hand, so that the protective groove 31 is dislodged from the fixed sleeve 29 or fitted onto the fixed sleeve 29 by the action of the threaded groove 30, thereby achieving the effect of protecting the rotating rod 28 and preventing the rotating rod 28 from being affected by wood chips. Example 7:

[0046] This embodiment provides a cutting device for log cutting. In addition to the technical solutions of the above embodiments, it also has the following technical features: the rotating rod 28 is rotatably connected to the main blade body 3, and one end of the rotating rod 28 has a hexagonal structure.

[0047] The rotating rod 28 is rotatably connected to the main blade body 3. One end of the rotating rod 28 has a hexagonal structure, which not only ensures the smoothness of the rotation adjustment process of the rotating rod 28, but also allows it to be operated with a standard hex wrench. The locking and unlocking of the main blade body 3 can be completed without special tools, which significantly improves the convenience of equipment maintenance. Example 8:

[0048] This embodiment provides a cutting device for log cutting. In addition to the technical solution of the above embodiment, it also has the following technical features: one end of the first bevel gear 22 is rotatably connected to the slide groove 18, and one end of the gear 25 is rotatably connected to the first gear groove 21.

[0049] One end of the first bevel gear 22 is rotatably connected to the slide groove 18, and one end of the gear 25 is rotatably connected to the first gear groove 21. This ensures that there is no jamming during the operation of each transmission component, and that the power transmission is smooth and reliable. At the same time, it reduces wear between transmission components and effectively extends the service life of the drive assembly. Example 9:

[0050] This embodiment provides a cutting device for log cutting. In addition to the technical solution of the above embodiment, it also has the following technical features: the screw 20 is located in the slide groove 18 and is rotatably connected to the slide groove 18; the threads on several screws 20 have the same direction of rotation and the same thread pitch.

[0051] Among them, the screw 20 is located in the slide groove 18 and is rotatably connected to the slide groove 18. The threads on several screws 20 have the same direction of rotation and the same thread pitch, which can ensure that several insert rods 19 move synchronously and at a uniform speed during the adjustment process, so that the locking force of each insert rod 19 on the insert block 5 is uniform and consistent, avoiding the tilting or loosening of the main blade body 3 due to uneven force, and further improving the reliability of the locking structure.

[0052] Working principle: When the user starts the cutting device 1, the cutting device 1 will drive the two output shafts 2 to rotate, and the two output shafts 2 will drive the two main blades 3 to rotate through the two inserts 5 respectively. When the two main blades 3 rotate, the two main blades 3 will drive the two cutting saw blades 13 to cut the log. At the same time, the two main blades 3 will drive several double-sided crushing blades 9 to rotate synchronously at high speed, which will crush the edge scraps and large sawdust generated during the cutting process into fine particles in an instant. The entire process of high-precision square cutting of logs, instant crushing of cutting residues and automatic chip removal is completed in one go, which fundamentally solves the technical pain points of low processing accuracy, easy deviation and cumbersome residue handling of traditional band saws. When the cutting saw blade 13 needs to be replaced, the user can use a tool to loosen several cutting saw blade fixing screws 14 to remove them from the main blade body 3, thus allowing the cutting saw blade 13 to be replaced. After replacement, the several cutting saw blade fixing screws 14 are reinserted into the cutting saw blade 13 and inserted into the main blade body 3, then rotated in the opposite direction to fix the cutting saw blade 13 to the main blade body 3, ensuring that the user can replace the cutting saw blade 13. When the user needs to replace the double-sided crushing blade 9, the user uses a tool to loosen the two positioning plug screws 11 and the two blades. Fixing screw 12 releases the fixation of blade cover 10 and double-sided crushing blade 9, allowing the user to remove the double-sided crushing blade 9 from the blade base 7 and blade cover 10 for replacement. After replacement, the user re-inserts the two positioning screws 11 and the two blade fixing screws 12 into the blade base 7, double-sided crushing blade 9 and blade cover 10, and uses a tool to reverse the two positioning screws 11 and the two blade fixing screws 12 to re-fix the double-sided crushing blade 9 between the blade base 7 and blade cover 10, and fixes the blade cover 10 on the blade base 7, ensuring that the user can replace the double-sided crushing blade 9. When the user needs to replace the main blade body 3, the user manually rotates the rotating rod 28, causing the rotating rod 28 to drive one of the gears 25 to rotate within one of the rotating slots 24. This causes one gear 25 to drive several other gears 25 to rotate via the gear ring 27. When the gears 25 rotate, one end of each gear 25 will drive several second bevel gears 23 to rotate within several first gear slots 21. In turn, the second bevel gears 23 will drive several first bevel gears 22 to rotate within the first gear slots 21. The first bevel gears 22 drive the screws 20 to rotate in the slides 18, and the insert rods 19 move along the slides 18 under the action of the screws 20. One end of the insert rods 19 can be inserted into the limiting grooves 17 or enter the slides 18 from the limiting grooves 17. This ensures that the user can quickly fix the main blade 3 on the insert block 5 or quickly release the main blade 3, allowing the user to replace the main blade 3.
